    In the current work, using upward spray and NaCl added water, the Leidenfrost effect is significantly minimised in an ultrafast regime by cooling on a hot moving plate, and the heat removal enhancement rate is achieved at 2.15 times of water. The salt deposition on the steel augments CHF(Critical Heat Flux) and IHF(Initial Heat Flux) by bridging the droplet and hot plate's air gap and enhancing the momentum diffusivity. With NaCl added to water, the achieved corrosion rate is 0.79 mm/year lower than the SDS and Na2CO3 additives. The mechanical property analysis of the post-treated steel plate ensures significant tensile strength and hardness
